Security Advisory

Bentley is committed to continuously investigating and rectifying security vulnerabilities affecting its products and services. Regular checks and updates are a part of our release process. In this version we have upgraded our Fortran compiler as part of this process.

EXECUTE Command

The EXECUTE command poses a security risk and is therefore not recommended for use. To maintain backward compatibility, the command is still supported but is deactivated by default. To activate it, refer to the CONTROL command in the User Interface Command Reference Manual Volume I: Solids & Structures.

 

AUI Features

Ribbon menu and updated icons

The AUI now includes larger ribbon menu icons in 32-bit color making it easier to see and understand the meaning of each tool.

GBODY8 Command

The following changes are made to the command to improve mesh quality and simplify the process:

MMFACE Command

The functionality of the command is improved. For more information, refer to MMFACE command in the User Interface Command Reference Manual Volume I: Solids & Structures.

 

ADINA Structures Features

New Explicit Bathe Time Integration Solution

A new and effective explicit time integration method b1/b2 - Bathe is implemented. The method is a one parameter scheme that accurately solves analysis problems of structural vibrations and wave propagations.  For more information, refer to Section 8.1.3 in the Theory and Modeling Guide, Volume I.  In addition, technical details can be found in the following publication:

Mohammad Mahdi Malakiyeh, Saeed Shojaee, Saleh Hamzehei-Javaran, Klaus-Jürgen Bathe, (2023), “The explicit b1/b2 - Bathe time integration method”, Computers and Structures, 286, 107092

Fiber-beam element

A fiber beam is a specialized type of beam element with cross-sections composed of multiple fibers. It originates from ADINA's standard beam element, retaining most theoretical aspects except those related to handling cross-section forces and deformations. While a standard beam cross-section can be selected from the cross-section library (such as Rectangular, Pipe, Box-beam, U-beam, I-beam, L-beam, and General), the cross-section of a fiber beam is formed by combining numerous fibers. Unlike the standard beam, which has a uniform material throughout the cross-section, the fiber beam allows different materials to be assigned to different fibers, offering greater flexibility. For more information, refer to Section 2.4.10 in the Theory and Modeling Guide, Volume I.

Steel Uniaxial model

The steel model is a uniaxial material model available for truss, link and fiber beam elements. The model described in this section is based on a bounding surface plasticity framework. This model captures key cyclic behaviors of structural and reinforcing steel, including: the sharp yield, yield plateau, and strain hardening behavior under monotonic loading; the Bauschinger effect, which results in a reduced yield stress when the loading direction reverses; cyclic hardening behavior, where maximum and minimum stresses increase upon cycling between constant strain levels; gradual stabilization to constant hysteretic loops during cycling; mean stress relaxation in cases of large inelastic cycles with non-zero mean strain.  For more information, refer to Section 3.21 in the Theory and Modeling Guide, Volume I.

Plastic-Fracturing (PF) Concrete Material Model

The Plastic-fracturing-concrete (PF-concrete) material model is designed to accurately represent the limiting behavior of concrete using plastic-fracturing theory and strain-based finite element methods. It incorporates several aspects for modeling concrete, including formulations for cracking, crack opening and closure, and crushing, similar to the solution implemented for the DF-concrete model. For tensile stress-strain behavior and tension-softening, it follows classical concrete theory as implemented in the DF-concrete as well. A new approach for compressive nonlinear behavior is implemented to achieve better response predictions with limit loads for practical engineering problems. For more information, refer to Section 3.7.3 in the Theory and Modeling Guide, Volume I.

Shell Analysis Results

The capability to store shell nodal forces and stresses/strains within the same analysis in the results database (ResultDB) file is now supported.

Drucker-Prager Material Model

Hardening behavior is added to the Drucker-Prager material model. For more details, refer to MATERIAL DRUCKER-PRAGER command in the User Interface Command Reference Manual Volume I: Solids & Structures.

Mohr-Coulomb Material Model

Hardening behavior is added to the Mohr-Coulomb material model. For more details, refer to MATERIAL MOHR-COULOMB command in the User Interface Command Reference Manual Volume I: Solids & Structures.

FREQUENCY Parameter for TIMEFUNCTION Command

A new parameter, FREQUENCY, added to the TIMEFUNCTION. It specifies whether frequency information is given in degrees/(unit time) or cycles/(unit time). For more information, refer to TIMEFUNCTION command in the User Interface Command Reference Manual Volume I: Solids & Structures.

Enhanced Rebar Meshing for 2D and 3D problems

The rebar feature has been enhanced and it can now handle more complex rebar arrangements for 2D and 3D applications. This is achieved through new added rebar parameter EXTENSION. New possible applications include for instance the ability to create 2D and 3D main rebar and stirrup loops or to model free ends of rebar.

 

CFD/FSI Features

Fully Developed Flow (FDF) boundary condition for CFD/FSI

The Fully Developed Flow (FDF) boundary condition is a significant recent advancement in the field of CFD. It enables high-quality boundary solutions for simulating accurate pressure drops and flow distributions in straight pipes, ducts, and channels over much shorter sections. It also provides robust boundary solutions for more complex flows in a wide range of applications. FDF boundary condition enhances both the efficiency and accuracy of fluid solutions. Refer to Section 3.4.3.16 in the Theory and Modeling Guide, Volume III.

 

Minor Enhancement & Corrections

Link element triad

AUI improvements made in the presentation of the element local system triad for link elements.

Centrifugal load error

AUI error when using centrifugal load together with load case scheme which prevented the .dat file from being saved and solved. In some versions the .dat file was generated and solved, but the combined loading results were absent.

RBE3 elements with general constraints

AUI failed to create DAT file when model contained RBE3 elements that use general constraints.

Restart file info

The restart file information displayed under "AUI > File > Restart File Info" was incomplete. As a workaround, please refer to the .out file of a restart run for the complete information.

Shell Analysis Results

Shell element sectional forces were calculated incorrectly for standard shell elements with variable thickness. The capability to store shell nodal forces and stresses/strains within the same analysis in the ResultDB file is now supported.

Beam bolts with PBFE

In ADINA Structures, using beam-bolts with potential-based fluid elements and mass-proportional loads resulted in incorrect results in the bolt step.

Shell nodal force results

There was an issue where reaction results and shell nodal force results were calculated incorrectly for standard shell elements using thermo-elastic-plastic and creep material. This error occurred only when shell nodal forces were requested instead of shell stresses.

Shell bending moment results

For shell elements (standard shell, membrane shell, bending shell and 6DOF shell) with a nonlinear elastic material model, the output of bending moments is incorrect when 'Calculate Midsurface Forces/Moments' is selected for midsurface results.

ADINA solver exits with an error message running older DAT file

Backward compatibility was not maintained when a data file (dat) created by AUI v23 was used in ADINA v24. This issue has now been resolved.
